Verified energy-support FAQ

No. It identifies routes worth checking from the answers provided. A council, energy supplier, Ofgem process or authorised installer makes the official decision.

No. WarmHome UK currently provides information and an indicative report. It does not promise an installer call, survey or installation.

Schemes differ by nation and some postcode areas cross borders. Asking directly is more reliable than guessing from a postcode prefix.

You can continue without an EPC. The result then warns that any EPC-dependent route still needs official confirmation. The government data API covers England and Wales, not all UK countries.

No. It is the wider government policy programme. The household route assessed here is the England-only Warm Homes: Local Grant.

Policy sets a £16,600 average cost cap across a project for energy-performance work and a separate £16,600 average cost cap across a project for low-carbon heat. The caps are not combined into a household entitlement, and neither is a guaranteed personal award.

The official route normally requires an England property privately owned by the applicant or landlord, EPC D to G, and household income usually £36,000 or less or another official benefit or postcode route. Council funding and checks still apply.

The official page says homeowners and tenants generally do not pay, but landlords may need to contribute. The council decides the final package and funding.

Ofgem says ECO is not a grant scheme. Larger suppliers have an obligation to deliver eligible improvements, but they decide whether to fund work, what to offer and whether a contribution is required.

The current end date is 31 December 2026.

Current direct routes include Universal Credit, Pension Credit Guarantee or Savings Credit, income-based JSA, income-related ESA, Income Support, Housing Benefit and Child Benefit with additional income caps.

They are not in Ofgem’s current direct ECO4 benefit list. A participating council may have a separate ECO4 Flex route using other household criteria.

No. EPC, tenure, technical suitability, supplier policy and available funding also matter.

Current support includes £7,500 for eligible air-to-water or ground-source heat pumps, £2,500 for eligible residential air-to-air heat pumps and £5,000 for eligible biomass. A £9,000 off-gas heat-pump uplift has separate time and property conditions.

An MCS-certified installer applies on behalf of the property owner in England or Wales.

Not necessarily. The voucher is deducted from the installer quote and the owner pays any balance.

Current Ofgem guidance says a valid EPC is no longer required for applications made from 28 April 2026.

No. It supports eligible low-carbon heating technologies, not a like-for-like gas-boiler replacement.

There is no reliable universal figure. Energy Saving Trust’s current 120mm-to-270mm top-up example is about £17 a year in Great Britain; a home with no insulation may have a different result.

Energy Saving Trust currently gives about £750 for no loft insulation to 270mm, £600 for a 120mm loft top-up, £2,200 for cavity wall insulation, and around £12,000 internal or £15,000 external solid-wall insulation for a typical three-bed semi.

Energy Saving Trust’s current typical reference is about £12,000 before support. Running costs depend on system design, insulation, tariffs and use.

Energy Saving Trust’s August 2026 reference is around 4.5kWp and £7,600. A home battery is typically around £5,000 to £8,000.

No. Current Energy Saving Trust examples range from about 9 years in London to 11–12 years in Stirling, but roof, shading, price, on-site use, export tariff and future energy prices change the outcome.
